rationale for ext2 vs reiserfs for /usr/portage and /var/tmp comes from
benchmarking tests, here :

Compare this fex :

You want to look at the 50k tables (mid page) where they are fairly well
tied, except when you look at %CPU.

Reiserfs has a -horrid- way of dealing with the processor, and requires
a lot of cpu munching.

Look one thread above this, subject:

Reiser has its uses, for a squid cache server fex.  But I wouldn't put
it even near a partition with data I value. it may be "stable" for
users, and so on.  that doesn't matter if the fsck tools are so horridly
handicapped that they cannot recover data without forcibly rebuilding
the tree.

Try doing "emerge sync" wait until its mid-process and press
alt+sysrq+b.  (cvs up is actually worse ;7 ) .  

As said, I ran reiserfs for a while, but won't ever do it again because
of how it cannot recover when it goes down the drain. 

 And if you really want to know how bad, dislodge the IDE cable some
while you're working on the disk. (I dont guarantee the drive will
survive though ;).  you get udma crc errors...  keep working as you
don't notice your disk does that, emerge -u system is a good thing since
you left it overnight...

Then come back, reinsert cable, reboot, and watch the show.



put short:   Reiser has performance, but uses CPU power more than
anything (not good when compiling).  And it can't recover data once
things really go down the drain.
